摘要:
The present invention relates to a multilayer conductive fiber having a core/shell structure, wherein the core contains nanotubes, in particular carbon nanotubes. The invention also relates to a method for producing said fiber by coextrusion and to the uses thereof. The invention finally relates to a composite material including the aforementioned multilayer composite fibers bonded together by weaving or using a polymer matrix.
摘要:
The invention relates to methods for controlling and improving the conductivity of thermoplastic polymer materials containing NTC, or for making said materials conductive while they are initially insulating. The present invention relates to a conducting composite material containing a thermoplastic polymer and carbon nanotubes (NTC), and to methods for preparing said conducting composite material, said methods comprising the injection moulding or extrusion at a temperature higher than the fusion temperature of said polymer, or a thermal post-treatment step of said composite material obtained by injection or extrusion.
摘要:
The présent invention pertains to the use of nanotubes of at least one chemical élément chosen from éléments of groups IHa, IVa and Va of the periodic table to improve the high température mechanical properties of a polymeric matrix comprising at least one semi-crystalline thermoplastic polymer.
摘要:
The invention relates to linear or star block copolymers, the preparation method thereof and the use of same in adhesive compositions, for example as a pressure-sensitive adhesive. The inventive copolymers are prepared by means of nitroxide-controlled radical polymerisation and have at least one soft block at Tg less than 0 DEG C and at least one hard block at Tg greater than ambient temperature.
